Buckshot vs slugs...?
I have taken multiple N TX hogs (200+ lbs) with 12 GA 00 buck shot...including several at ~60 yards with 3" (high brass). I use a Weatherby 1" extension full choke which really helps with tighter longer range patterns. I find the swing action of an open sight works best for me, as I am a lifelong upland bird hunter...and the shooting from a standing position suits my muscle memory the best.
Slugs are very effective, but shot placement and hitting running second shots are more difficult.
I do not hunt out of a vehicle, so I do not have your experience to relate to on the difference on the lethal effectiveness of the 2 loads.
Normally I walk my feeders or I just wait in my blind until the game cameras notices goes off and then I stalk down to shoot. I also utilize a motion activate pig lite for night time hunting...with the same effectiveness with 12 GA 00 buck shot...buckshot makes the shot placement a whole lot easier.
Note - I have taken the upland game plug out of my Weatherby to allow 5 shells so I get to shoot multiple targets as they run after the first shot. Gotta' to love a semi auto hog hunting weapon.
Here are some pics from 3 feral hogs taken in the mid morning this week with 00 buck shot.
These 3 weighed over 700 lbs in total...and they all dropped where they were hit !
